Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43977   clinical trials with a EudraCT protocol, of which   7312   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Title: Cough Monitoring Substudy
    Date and Version: Not applicable (part of the main protocol)
    Objective 1: To assess the effects of Mitiperstat (AZD4831) compared to placebo on change in cough frequency measured over a 24-hour period between start of treatment and Week 12.
    Objective 2: To investigate whether cough frequency is associated with lung function (eg. PEF, FEV1), cough/COPD symptom scores (eg. BCSS, CAT and Cough VAS) and sputum/blood biomarkers (eg. MPO concentration, neutrophil activation markers).
    E.3Principal inclusion criteria
    1. Confirmed primary diagnosis of moderate to severe COPD as per FEV1/FVC < 0.7, and post-BD FEV1 ≥ 25% predicted)
    2. Current or ex-smokers with a tobacco history of ≥ 10 pack-years
    3. High risk of exacerbations as defined by any one of the following:
    (a) A documented history of ≥ 1 moderate or severe AECOPD requiring systemic corticosteroids and/or antibiotics for at least 3 days’ duration (or 1 injection of Depot formulation), or hospitalisation for reason of AECOPD in the 24 months prior to screening or
    (b) Frequent productive cough, defined as a positive response to both of the following questions:
    • Over the past 3 months, I have coughed at least several days a week
    • Over the past 3 months, I have brought up phlegm (sputum) at least several days a week, or
    (c) Post-BD FEV1 < 50% predicted.
    4. Clinically stable and free from an exacerbation of COPD for 1 month prior to SV1 (screening) and prior to Day 1.

Triple therapy may consist of an appropriate combination of ICS + LABA + LAMA. Dual therapy consists of either inhaled ICS/LABA or LABA + LAMA where the treating physician deems the participant unsuitable for ICS (eg, blood eosinophil count ≤ 100 cells/µL on 2 separate occasions, or on the basis of previous or perceived risk of significant AEs from ICS-based therapy, such as previous episodes of pneumonia or significant oral candidiasis).
    E.4Principal exclusion criteria

    5. Current diagnosis of hyperthyroidism, uncontrolled hypothyroidism (including but not limited to TSH ≥ 10 mIU/L.), or any clinically significant thyroid disease.
    6. Participant who is going to start or finish intensive COPD rehabilitation program at anytime during study period. Participants can be recruited immediately following the completion of their COPD rehabilitation program.
